Claims.

The present invention relates to rocker attachment units for chairs, and particularly to such units which include connecting elements for the chairs, which connecting elements are disposed crosswise in the rocker attachment units.

In applicants copending patent application, Serial No. 158,427, filed April 27, 1950, a rocking chair has been disclosed which has upwardly extending leg portions extending into horizontal base portions and which rocking chair comprises a base having a pair of spaced rockers which may be connected by cross braces and the embodiments shown in this copending patent application include preferably longitudinal members which are mounted on the base to support the longitudinally extending horizontal portions of the legs of a chair.

Since such structure is more or less limited to chairs which have longitudinally extending leg portions, the use of the rocker attachment appears to be limited to such specific chairs.

It is, therefore; an object of the present invention to provide a rocker attachment unit for a chair which is equipped with crosswise disposed members received or supported by two crosswise disposed elements secured to the rocker attachment unit.

It is a further object of the present invention to provide a rocker attachment unit for a chair having preferably two crosswise disposed mernf bers which are received b two crosswise disposed channel members secured to the rocker attachment unit.

It is a further object of the present invention o provide a rocker attachment unit for a chair having preferably two crosswise disposed members one of which is received by a channel member secured to the rocker attachment unit, while the other crosswise disposed member of the chair rests on the rocker attachment unit.

It is yet another object of the present invention to provide a rocker attachment unit for a chair having preferably two crosswise disposed members which are received or supported by the rocker structure.

It is also another object of the present invention to provide locking means for releasably securing the chair to the rocker attachment unit.

With these and other objects in View which will become apparent in the following detailed description, the present invention will be understood in connection with the following drawings, in which:

Figure 1 is a front perspective view of the rock ing chair constructed in accordance with the present invention;

Fig. 2 is a front elevation thereof;

Fig. 3 is a side elevation thereof;

Figs. 4 and 5 are fragmentary side elevations of two additional embodiments of the connecting means between the chair and the rocker attachment;

Fig. 6 is a side elevation of a rocking chair in connection with a lawn chair;

Fig. 7 is a side elevation of a rocking chair with a lawn chair, similar to that shown in Fig. 6;

Fig. 3 is a fragmentary side elevation of the rocking chair shown in Fig. 7, disclosing a variation thereof; and

Fig. 9 is a fragmentary side elevation or the rocking chair shown in Fig. '7, disclosing a further variation thereof.

Referring now to the drawing, and particularly to Figs. 1-3, the present device comprises a chair I having a seat 2, a back 3, and upwardly directed leg portions 4 which are bent to form two substantially parallel horizontally disposed leg portions 5, the latter engaging the ground when used as a chair. The horizontally disposed leg portions are connected at the rear end by a preferably integral crosswise disposed member 5a. The front ends of the horizontally disposed leg portions are likewise connected by a crosswise disposed member 512 which is secured to the leg portions by any suitable means, as by welding.

The rocker attachment 6 comprises a base which consists of a pair of spaced rockers 1 which may be connected by braces 8, but may be dis pensed with, since other elements may be used as connecting and spacing means for the rockers. One example for such elements is a pair of parallel channel members 9 and I0, preferably of u-shape, which are crosswise disposed and secured to the rockers 1 by any suitable means. The channel members 9 and [0 receive the crosswise disposed members 5d and 5b of the chair i, when combined with the rocker attachment unit. This is achieved by a cross sliding movement of the members 5a and 5b of the chair I into the channel members 9 and I0 of the rocker attachment. In order to secure the members 511 and 5b in the channel members 9 and ID, a spring bolt H of conventional structure may be provided in one or both channel members 9 and I0, which spring bolt H enters a dent or bore (not shown) of the cross members 5a and 51) (see Fig. 6 of my Patent 2,516,774).

It isto' be understood that instead of providing a channel member 561' or 519 across the rockers,

it is also possible to substitute short channel pieces in coaxial arrangement on each one of the rockers I, in which case, the braces 8 serve as sufficient connecting and spacing means for the rockers.

While particularly Figs. 1-3 disclose a rocker attachment for a chair which is equipped with two crosswise disposed parallel channel members 9 and Ill, the embodiment shown in Fig. 4 comprises a rocker attachment 6', the rockers 1 of which may be connected by braces 8. A crosswise arranged single channel member 9 is secured to the rockers l", which channel member 9' receives the cross member 5b of the chair l'. The other cross member 5a rests on the rockers 1' adjacent a cross member Ill which may be of tubular shape and a spring bolt ll may be again provided to secure releasably the cross member 5b to the channel member 9 as well as the cross member 5a to the cross member l.

Fig. discloses a still further embodiment of supporting the chair I on the rocker attachment which does not include any channel members. According to this arrangement, the rocker attachment 6 comprises again a base having two spaced rockers l which may be connected by braces 3 Two preferably tubular parallel cross members 9 and are supported and secured to the base at their front and rear end, respectively.

The chair is equipped with a front cross member 51) and with a rear cross member 503, both members resting on the rocker l engaging the respective front and rear cross members 9 and I0 Spring bolts ll may serve to secure releasably the cross member 9 to the cross member 5a and the cross member Hi to the cross member 529 The rocking chair disclosed in Figs. 1-5 shows three different connecting mean of a tubular chair having horizontal leg portions connected with a rocker attachment unit. Fig. 6 shows that the same rocker attachment unit can be used for any type of chair as long as the lower ends of its legs are equipped with a front and rear cross member to cooperate with complementary channel members, one channel member and a cross bar or two cross bars. Fig. 6 shows the application of this principle for a lawn chair I which in conventional manner has crosswise disposed legs 4 the lower ends of which are equipped with cross members 5a and 511 respectively. Merely by example, the rocker attachment unit 6 is shown with a channel member 9 and I9 near its front and rear ends, respectively. The rocker attachment unit 6 comprises again the rockers l which may be secured together and spaced apart by braces 8 In connected position, the channel member 9 receives the cross member 512 and the channel member I 0 receives the cross member 5a As indicated above, the same variations may be used in connection with a lawn chair, namely, either one channel only and one cross member, or merely two cross members may be provided and secured to the rocker 1 Referring now to Fig. '7 of the drawing, a lawn chair i which has a substantially U-shaped rear member forming the rear legs 40 and a substantially U-shaped front member forming the front legs 4b", the respective bases 5:1 and 5b of the two U-shaped members engaging the ground when used as ordinary beach chair.

The rocker attachment unit 6 comprises again a base consisting of two rockers l and in the example shown in Fig. '7, a pair of preferably substantially U-shaped channel members 9 and ID are secured to the rockers 1 The channel members 9 and I0 are adapted to receive the respective bases 5b and 5a of the U-shaped members.

In the embodiment shown in Fig. 8, which is similar to that shown in Fig. 7, the base comprises again two rockers 1 to which two preferably tubular members 9a and NW are secured near the front end and rear end, respectively. The bases 5a and 512 of the U-shaped members rest on the rockers 1 adjacent the respective members 9a and l0a and spring bolts (not shown) may retain the said bases in their position on the base.

In the embodiment shown in Fig. 9, which is similar to that shown in Fig. '7, the chair shows likewise a base which comprises again two rockers I to which a channel member 9b is secured and disposed crosswise near one end thereof and a preferably tubular member Hlb is secured and disposed crosswise near the other end thereof. The channel member 971* is adapted to receive the base 5b of the U-shaped member forming the front legs of the lawn chair, while the base 511 of the other shaped member rests on the rockers 1 adjacent the tubular member lflb Spring bolts (not shown) may be again provided to retain the lawn chair on the rocking base.

While I have disclosed several embodiments of the present invention, it is to be understood that these embodiments are given by example only and not in a limiting sense, the scope of the invention being determined by the claims.
